Fluoraldehyde crystals are o-phthalaldehyde (OPA), a highly sensitive fluorescent derivatization reagent for peptide or amino acid detection and quantitation in HPLC.


  • For pre- or post-column amino acid derivatization for fluorescent detection and quantitation
  • Reacts with all primary amine-containing analytes to yield fluorescent isoindole derivatives
  • Provides an accurate measure of both composition and absolute protein-peptide content
  • Ideal for work with recombinant proteins and synthetic peptides
  • Can be used for fluorescent protein or peptide assay
  • Can be prepared as a stable aqueous solution in borate


Fluoraldehyde crystals are a purified, fluorogenic-grade preparation of o-phthalaldehyde (OPA). Fluoraldehyde reagent solution contains OPA which is supplied ready to use and enables fast quantitation of proteins or peptides in solution.
